Disclosed herein are a display device and a mobile terminal device including the same, which include a display panel including a screen in which a plurality of display pixels which are sequentially scanned, and a plurality of sensor pixels which are exposed to a light during an exposure time to convert the light into an electric current are disposed. While the display pixels disposed in the first area of the screen are scanned, the sensor pixels are exposed. While the display pixels in the second area of the screen are scanned, sensor data is output from the sensor pixels and then the sensor pixels are initialized.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The display device of claim 1, wherein a low potential power voltage and a pixel driving voltage are applied to a pixel circuit driving the plurality of display pixels and a photosensor drive circuit driving the plurality of sensor pixels.
3. The display device of claim 2, wherein a cathode electrode of a light-emitting element of a display pixel from the plurality of display pixels and a cathode electrode of a photodiode of a sensor pixel from the plurality of sensor pixels share a same metal electrode.
4. The display device of claim 2, wherein an anode electrode of a light-emitting element of a display pixel from the plurality of display pixels and an anode electrode of a photodiode of a sensor pixel from the plurality of sensor pixels are formed on a same layer and include metal patterns separated from each other.
5. The display device of claim 1, wherein a photodiode of a sensor pixel from the plurality of sensor pixels includes an organic photodiode.
8. The display device of claim 7, wherein the pixel circuit and the photosensor drive circuit are initialized due to the initialization voltage.
12. The display device of claim 10, wherein each of the driving element and the first switching element to the sixth switching element of the pixel circuit and each of the first-S switching element to the fourth-S switching element of the photosensor drive circuit includes a p-channel transistor.
14. The display device of claim 7, wherein a gate-on voltage section of the exposure signal overlaps the scan pulse generated before reaching the second area.
